Hi all, I’ve written an IDL script to reproject and “snap”, or register at the pixel level, imagery to a standard raster. The standard raster is much larger in extent than a Landsat image, and when I use ENVIGridDefinition::Intersection to compute the intersection, the output is always registered to the smaller of the two inputs, though the output extent is essentially correct (it is offset by a sub-pixel distance). Is there a way to force registration to the larger input?

Thank you, Matt Vernier
